I think that's all. Might have missed one or two, as the books have completely different layouts. AC9 is divided into sections by monster type, while DRM2 just lists everything alphabetically.

AC9's Table of Contents also has every monster listed multiple times if it's got multiple names, or multiple words (Grey Philosopher is listed as is, but also as Philosopher, Grey later). DMR2 also collects some of the independent listings of AC9 under groups, such as the prehistoric animals.
